I need help! Base for Greenhouse

Posted: 28/05/2013 at 12:25

Although i can't help with advice - sorry - intrested in your plight. As im currently in a greenhouse base situation. I have a concrete base and ..due to 'experiance' of banging my head on the greenhouse ( im only 5ft 10 mind you ) i chose to heighten the thing. Two flat breezeblocks laid - all straight and square ( i hope ).

Now..i have the doorway situation. Do I cut the base/thin aluminum strip for doorway ( so no need for horrible step down / up ) and risk...weakening the structure??? or not.

Wall is built..with 2ft gap for door..and small jigsaw in i sense my brain is saying go for it...but im thinking of the ground frost and extra warmth a short wall will perhaps bring...realise breezeblocks soak up the water cant win.

Sand...on the floor..pebbles...etc..imagine all the compost etc falling into that..ants..bugs etc....I'm raising one section slightly and filling with a little compost - which in theory I can then clean/reuse. Other side slabs..simple. No messing.

Thanks Skyrunner/Fairygirl for replyies. Glad to hear Sky that not just me then wanting to heighten te greenhouse. easy enough to screw/bolt down the base. I suppose my own real question then is...How big an issue would it be for me t cut the base/frame where the door currently would sit?

I mean..seriously..will this really weaken the structre ? End of the day the doorway itself divides up the greenhouse doesnt it...a thin strip of aluminim wouldnt really effect the overal structure of the greenhouse would it?

I will take also be using a hacksaw to cut the base etc..wish me luck. APPRECIATE any replies...before I set about an 'destroy' my new greenhouse! ...thanks.

At the moment my main concern is bolting base to breezeblock and cutting the alminum esp the base section. 

Re the doorframe and contacting tig welders etc..thats all out of my league and budget im afraid! I will mess about with the door iteself/extend etc

Photos taken - still to upload however - at the moment its just a wouldnt be of much help i dont think..saying that...i will tomorrow upload a photo.

Essentially, a breezeblock wall, 2 high ( laying flat ), have measured and left a gap for where the door will be.

The base will laying on top of the breezeblock wall, roughly laying in the middle of the breezeblock..apart from at the front ( because obviously it needs to be level with the front for the sliding door to slide ) .

So, all I'm asking is...(a) Will cutting 2 ft of the base and 2ft of the thin alminum frame ( for the door ) weaken the structure?

(b) What shall I use to bolt down the base onto the breezeblocks? Tempted to drill a big hole an insert/cement a few of the 'spikes'. Also have to rawplug??? the base into the wall. Ok to do that?? Do I simply drill through the aluminum base? Doesnt appear to be any pre-drilled holes.

Will worry about lengthing the sliding door/sealing it/ makng a make-shift slider..another time. Main concern is cutting this base/frame. ( and any decent tool to cut alminum??

Thanks again.

Brummieben, thank you for you reply..and keeping this thread alive!! The two high breezeblock wall is still drying out..and intend on painting it..but this time next week I should have my greenhouse up and running!

Now - you mentioned about the greenhouse gets its strength from the...base? the frame?...naturally this is a worry...would be very intrested to hear from anyone else regarding you mentioned...once I cut the base and the thinner alminumin frame where the door ( sliding door ) goes..well..thats to speak...cant go back.

I to nothing about construction..would surely...the thin strip where the door goes..surely that isnt going to give the greehouse strength...i mean...IF i secure the base...screw it much as possible..and yes i also thought about inserting some of the 'spikes' into the breezeblock and then cementing them in... but surely...once the actual frame is placed on top of the will be as secure as theres a 2 foot gap missing...thoughts MORE THAN WELCOME.

I have it in my head to do this..ive left a gap for the door..i dont want a step in..period! ...I know..more fool me!!

A DREMEL...should I be buying this tool? to cut the ..base etc? Will check fine toothed hacksaw.

So..any thoughts attaching the base to the breezeblock i simply drill into the base? easy to do....or not? and aside from a few spikes I may try to cement in...for a start the front of the greenhouse is going to sit exactly on the very edge of the beezeblock wall..hase too because of the sliding door i rawplug it as well in places?

Once again all thoughts more than welcome..and very intrested to know others thoughts about comprimising the structure if i cut a gap for the door.

Update - a while back i questioned about erecting a 6 x 10 ft glass greenhouse - sitting it on breezeblocks to give it extra height..and also not wanting a 'step in' instead extending the length of the door etc..

I received some very helpful replies from various members.

I have now laid to rows of breezeblocks ( med - high density ) laying them flat and crucially..hopefully..all square and level!

My question is this...I want to bolt onto the breezeblocks ( once cement is dry etc ) the 'aluminum?' base which the greenhouse came with. Realise I dont have to do this and could attach frame straight onto my level breezeblock wall..but seeing as the whole point was to add height may as well use the base.

So - How do I attach the base to the breezeblock wall? Can I simply...drill?? into the aluminum base ( easy? ) and raw plug the breezeblocks? Any ideas? best...strongest method ? Any particular screw??  a normal..wall rawplug...?

The greenhouse came with...along with typical complicated instructions!!... 6 metal..I call them 'spikes' but just metal guessing i should..if i could of..cement/stuck into the ground. Annoyingly the metal 'spikes' are for the Im not going to be using them..I still HAVE TO cut the metal 'spikes' in order to use the piece with the 2 screw holes which are needed as corners for the base. I mean all this..because..Im not 100% thats what they are for? Any thoughts? Came in the base box, 6 metal 'pieces' about 12 clearly meant for the corners of the base i just cut these? question..quickie if you know the answer..cutting aluminum. Not just the unwanted portion of the 'spikes/metal pieces' but part of the Base where the door goes dont want a step a 2 ft portion needs to go. A little saw do the job?

Thoughts..musings...answers...more than welcome. Thanks for your times. Waiting on breezeblock wall to dry out before i start next stage..and yes..have taken photos to share..once all up and level etc etc

Fairygirl - i figured it was one way to get a reply to this thread and it worked! Bob really has helped - my plan will be put into practice shortly. Glad to read Bob about weight of door. Flicking through greenhouse instructions ( they really are bad ) i see there is a wall for the slider etc.. all sorted. I think I will film/photo part of its construction and youtube it or something. Disappointed looking on youtube at others efforts..would of thought be more examples of a greenhouse on bricks etc

Anyway thanks again. I will indeed build greenhouse, and cut the al. frame once complete.

Bobthegardener THANKS for your time/trouble replying to this. I will definately take this on board and follow it too the letter. Your reply is better than the greenhouse instructions I have!

Whilst have you final thing. I intend to make things a little difficult for myself - again I am a man afterall!! - once this greenhouse is on the breezeblocks I intend not to have a step in / out. Instead...i intend to cut the base /  build the wall with a gap. So..basically the sliding door only needs to be extended so i can walk in / out with ease.

I know some of the problems I may have..aka, the slider at the bottom and extending the door itself. But do you think this is not really much of an issue..and do-able.

Surely, all im doing is..sticking the slider / or buy another make-shift one - and stick it at the bottom of the wall..and then simply extend ( bolt aluminum pieces ) onto my existing door. Wouldnt be extending by much ( two flat breezeblocks worth and a base I suppose ).

I know..a lot of effort/time/money for simply a short wall..but..well...its in my head..and im going to do it. Your thought welcome...just any problems you see I might come across. Intend to do this project - right -.

Excuse me sir..yes you..I'm talking to you - the chap with the greenhouse, flatcap and fishermans jacket bursting with handy little tools poking out...your advice is much needed.

Im a idiot. There I've said it. An idiot with drills, hammers..manly stuff..but, like all men, I do have a

I have a 6ft x 10ft greenhouse - yet to be erected. I have a concrete base. I want to lay two high ( flat ) breezeblocks and sit my greenhouse on top of this. I want to do this for two reasons, (a) my concrete base isnt level..hopefully my breezeblock wall will be! and (b) height. I always recall my grandads, hitting his head on the grape vines which ran everywhere/tied to every rafter..

My question(s), I have the greenhouse base. How do I secure this base to my breezeblock wall?

It seems to come with some poles which ideally I'd cement into the ground. Obviously I cant really do this do i simply..drill holes in the base willy nilly..and raw plug it too my breezeblock wall? Use concrete screws?  Your advice is needed please!!

I suppose I dont even need the base..but then..seeing as I have it..and it would give me a fraction more height. I weakening my structure by using the base..on a breezeblock wall?

Finally, the breezeblocks themselves...assuming they need to be a certain type. I know they crumble easy!...

Any any men! out there ( women too ) with any answers to these little questions would be muchly welcome.

Thanks for your time, appreciate any replies.
