Why Waterproof?


The importance of quality waterproofing can’t be overstated: it accounts for 2-3% of a building’s construction costs, but faulty waterproofing causes 80% of building defects. Poor waterproofing can lead to cracks, mould, and structural afflictions like concrete cancer. These issues can render buildings unsafe or even uninhabitable, creating liability and insurance issues for landlords and shrinking your home’s resale value. Water leaks also damage carpeting, furniture, and other possessions.


Even if you already have waterproofing, it is important to maintain it and fix tiny leaks and cracks immediately. Call the professionals at ASG to keep your home dry and safe from water damage.
