that substance is clorine
The material you are likely referring to is called shotcrete, not shockcrete. Shock-crete is a flooring material and not used for swimming pools that I know of. Shotcrete is sprayed onto surfaces (like pools) that contains a primer and a type of polyurethane topcoat that contains an aggregate that finishes off looking like concrete in most applications. it is used mainly to apply monolithic linings that have a good chemical resistance. it is often used in pools, tunnels, etc., much like gunite i think its is concrete injected into the ground to firm up supports and the ground.
they need white chalk or any kind of regular chalk not like 3 d or colored chalk
Wood wall pools will often deteriorate faster than traditional galganized steel wall vinyl pools. Vinyl pools are the most economical where as concrete pools tend to be more luxurious. If you want to see a side by side comparison of all different types of swimming pools you can choose from at www.BuyPool.ca which is an article comparing the purchasing quality of: -Vinyl liner abover ground pools -Vinyl liner in ground pools -Concrete or gunite in ground pools -Fibreglass pools

Usually, the best and easiest way to determine is by looking at the prices: The higher the price, the better the pool. Stainless steel may be the best. But steel will be affected by chlorine and may rust eventually. Aliminum does not rust. Aluminum by nature is very soft, unless it is an "alloy," which would make it too rigid for above-ground pool construction. Above-ground pools need a certain amount of flexibility to accommodate water movement and temperature changes. It is also important is to make sure of the gauge of the walls! If the walls are not of at least 30 gauge, and have a deep corrugation (ridges in the wall) they not last as well.
