Lay it between the excavated ground and the liner before filling to reduce the risk of liner failure at the pond floor and side walls.\u003c\/p\u003e\n\n\u003ch3\u003eProtection Layer That Extends Liner Life\u003c\/h3\u003e\n\u003cp\u003eEPDM liner is strong and flexible, but it is not puncture-proof against sharp substrate objects that shift under the weight of water. Underlayment distributes load across a broader area, cushions the liner against point contact, and blocks roots from growing up through the liner after installation. The 5' x 10' size suits small to medium pond floors, koi pond side wall protection, and rock stream sections where individual pieces are easier to manage than a large roll.\u003c\/p\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5' x 10' (1.5 m x 3 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoverage\u003c\/td\u003e\n\u003ctd\u003e50 sq ft (4.6 sq m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eNon-woven geotextile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePairs With\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/firestone-pondgard-45-mil-1-14-mm-epdm-pond-liner\"\u003eFirestone PondGard EPDM Liner\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cp\u003eClear the excavation of sharp rocks and protruding roots before laying underlayment.
