Clean off with a wire brush all surfaces and any steel and pipe work within the area up to a radius of 1.5 metres from the furthest extent of suspected infection. Remove from the building all dust and debris ensuing from the work. Apply fungicide to all such masonry, concrete and earth surfaces at the specified rate. Apply two generous coats of ...

One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Water reducers offer several advantages in their use, listed below: reduces the water content by 5-10%; decreases the concrete porosity; increases the concrete strength by up to 25% (as less water is required for the concrete mixture to remain workable) increases the workability (assuming the amount of free water remains constant)

Curing is intended to maintain moist conditions at the surface of concrete. It can be done by letting the formworks in place for a longer time, or by applying a hydrophobic thin film of an oily product (curing compound) at the concrete surface (e.g., for large slabs or rafts) to minimize water evaporation. Drying shrinkage
A crack or cracks propagating from near the edge of the log towards the centre, usually along the line of the medullary rays, causing the wood to shrink more at right angles to the medullary rays than along them, causing warping of anything made from the wood. The cause is often rapid or uneven seasoning, causing the outside of the log to ...
