“This is just a short note to thank you and all others associated with Mainmark’s work at this address.

The challenge for home owners and developers undertaking earthquake strengthening works is to consider both ground strength and building behaviour so that
How extreme weather can affect your home’s foundations
Extreme weather events, natural disasters and extended dry spells have a significant impact on the ground and subsequently, on building foundations.
