Answers Before You Book
Frequently Asked Questions
Why does cement mortar crack again when used to fill roof cracks?
Cement mortar is completely rigid and shrinks as it cures. When the roof expands in the heat, the rigid patch simply splits open. Only flexible elastomeric polymers can move with the roof.
What is the purpose of fiberglass mesh over cracks?
The mesh acts like reinforcing fabric, distributing structural movement stress over a wider area so the waterproof sealant never tears.
Can roof crack treatment be done on tiled terraces?
Yes! We router out cracked grout lines and joint lines with diamond blades and fill with flexible polyurethane joint sealant.
How long does a crack repair take to dry?
Polymer crack sealants skin over in 2 hours and achieve full cure within 24 hours.
