친수성 복합 구조물은, 3DL 구조물을 폴리우레탄 발포체 제형으로 함침시키고 제형을 경화시켜 3DL 구조물 내의 공간을 차지하는 발포체를 생성함으로써 제조된다. 상기 복합 구조물은 압축력 하에서도 물을 보유하기 위한 유래없는 양호한 수용력을 갖는다. 이들은 또한 물로 포화될 때 최대로 중간 정도의 팽윤을 나타낸다. 상기 발포체는 물 격납 시스템 예컨대 녹색 루프(green roof) 또는 청색 루프(blue roof) 시스템의 층으로서 유용하다. Hydrophilic composite structures are made by impregnating a 3DL structure with a polyurethane foam formulation and curing the formulation to produce a foam that occupies the spaces in the 3DL structure. The composite structures have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.
