· Concrete (FC) is made by mixing into mortar. The mortar is a cement mix with sand and water. As a result you end up with a mix that is lighter than "normal" concrete. The mass or density as we call it here (weight per cubic meter) depends on how much is added to the mortar.

Therefore if the wall will be subject to freeze/thaw cycles or if the surrounding soil contains corrosive materials negative side waterproofing is not a permanent option. Hydrostatic pressure is a major concern

When steel corrodes the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete which can eventually cause cracking delamination and spalling.
Chat Online· Many hobbyists use a pointed waste remover inserted down past both the substrate drainage layers (against a side) to access and remove water. A slightly easier siphon-access point can be added during initial construction by placing a 3/8" tube through the substrate screen separator and down to the bottom of the drainage layer.
