Structural Engineers
Following a catastrophic failure of a deck in Victoria, we’re once again reminding homeonwners and landlords to have the decks and verandahs on their houses and investment properties checked regularly by a professional.
Our Australian climate is very harsh and even the most durable construction materials will eventually degrade. The defects might not be visually obvious to you – so have a professional Check your Deck!
Can termites enter your house through cracks in your concrete slab?
According to research by the Cement and Concrete Association of Australia, a concrete slab designed and built in accordance with our current footing and slab standard AS2870 should keep termites out.
According to the CCAA data sheet, termites can’t get through cracks less than 1.4mm wide. Even though termites are smaller than that, they don’t like the rough concrete edges and have to mud line the crack to make it through.
So if your house slab is designed by a structural engineer to comply with AS2870, the Australian code for residential footings and slabs, then termites should not be able to enter your house through cracks in the slab.

Cornell Engineers was asked to quote a job recently where a car collided with a house. The damage had already been repaired but the owner started noticing:
These issues sound a lot like slab heave to me.
Renovating or building? These are my favourite five Sika construction chemicals that you’ll need for your next home renovation.
Fresh update! This page features our favourite Sika products; but the best way to get hold of a Sika product is to contact Sika directly. Check out this link:

If you’re patching cracked or broken concrete, Sika MonoTop Primer is what you apply to the old concrete first to make sure the new concrete sticks. Brush, roller or spray on – it’s easy to apply and will improve the bond between old and new concrete.

Multi-purpose flexible joint sealant for use inside and out. Seal the gap in brick control joints, around windows and doors and wall and floor penetrations.
This stuff sticks to concrete, brick, tiles, moist metal and most timber.
My favourite use for Sikaflex-Pro is to seal the gap between concrete paths and brickwork walls to prevent water running into the ground adjacent to house footings. It’s great because, when installed correctly, the sealant flexes open and closed without tearing.

If you’re building a retaining wall or a basement then you need to make sure water won’t come through your wall. SikaTite-BE is a water based bitumen emulsion that can be applied on the soil side of the wall. Spray, roller or brush on.
When I specify a bitumen based waterproofing membrane – this is the black stuff I’m thinking of. I also like to specify it as a treatment for DuraGal galvanised steel to stop it rusting where it is in contact with concrete.
A range of coloured silicone sealants to match the colours of your kitchens and bathrooms. These arty-farty colours will blend in nicely with the look you’ve got going.
Seal the gap behind the new kitchen bench and along the side of your new bathroom vanity. So much more in sync with the vibe than sticking to white, colours like Taupe, Ivory, Pewter and Stone! Pretty fancy and jut perfect for your renovation.
Wanna get stuck? DIY renovators that want to stick something to something else – or itself – will love this stuff. Handy aerosol adhesive for multipurpose sticking.
Please don’t use it to fix plasterboard to a wall or to glue coins to the footpath – it’s more suitable for art and craft, repairs, and making stuff. Those TV renovators probably use tonnes of this stuff.
