Termites And Cracked Slabs

Are you worried that termites could enter your house through cracks in the slab?

Well, it’s a possibility but 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 the little critters 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.

Sika MonoTop-Primer

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.

Sikaflex-Pro

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.

SikaTite-BE

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.

Contact Sika directly.

Sikasil C AP

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.

SikaBond-SprayFix

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.
