1. Diagnose - Often leaking basements are leaking from multiple entry points. The most common is referred to as the 'joint', which is where the wall meets the concrete slab. When a basement leaks, it is generally because of defective waterproofing during construction. The joint is the weakest point of any basement construction and specific treatment is required to seal the joint from the negatve side (the side where the water pressure is not present. In addition to the jont, poorly waterproofed below ground structures can seep, whereby water comes through the wall at higher levels of the wall than the joint, and always below soil level. The soil pressed against the wall surfaces is filled with moisture which levels rise and fall as the water table and ground water levels rise and fall.Typically we diagnose the issue with a mixture of flood testing and thermal imaging cameras which seek out temperature differentials.
Work scope - Once we have identified the entry points in the leaking basement, we can provide the home owner with a wrutten scope of works for the required and correct treatment. Ins ome instances the scope can be undertaken by the property owner but in others specialised eqyuipoment may be required. If that is the case (specialised equipment) we can put you in touch with a company which can provide this specialised service for you.For further information or to bokk a dam inspection, John can be contacted on 0409 191 209 or via email.
