A kit for forming a secondary confinement installation for protecting earth from contamination due to leakage and spills from pipelines in small installations, such as service stations. The kit includes long trough sections and short connector sections with joints therebetween which maintain a level floor. The connector sections may have various shapes, such as right angle sections, half-right angle sections, T-sections, as well as a few special purpose sections. The special purpose sections include a sump section located at the low point of the installation, a dispenser unit section intended to provide catch basis for fluid dispensers and box sections which protect pipe egress zones at storage tanks. At installation time, the sections are supported by a bed of aggregate material, the pipe lines positioned and the trough sections and connector sections are filled with aggregate material and then cover members are set atop the sections, the cover sections having a vapor barrier member over the edge where the cover member and upper sidewalls of the trough and connector sections meet. Any fluid leaking from the pipelines flows toward a sump section where a check tube is provided for monitoring leaks.
