Need home use non-concrete playground surface?

Question:Commercilal rubber matrix playgrounds are nice but very expensive. Need something for pool deck that's waterproof (rain water must run off away from pool) and semi-flexible (won't crack).

Pool is in a small backyard formed by back-filling a large, 13 foot high concrete block retaining wall with soil. Can't let heavy rains saturate the D.G. soil or wall will crack from hydraulic pressure. (Already had small crack because soil got saturated in heavy rains.) Thanks.

Answers:
if thats the case, sooner or later your wall may give up even if you put water insulations. your retaining wall may have been designed in substandard procedures.

if you can. make holes on your retaining walls so water would just pass thru it. best way in making this is to drill a hole about 2.5 inch in diameter 1.5 meters apart. (not in a straight horizontal line) and then inser a 1 1/4" dia pipe thru it to the entire span.

if you think it wouldnt be possible, then, you should have another pool that is safer enough for you and your poolmates to swim.

i could not give you assurance of just waterproofing your deck
