The Sentry Sump System has been designed to complement the Oldroyd Xv Clear studded membrane system and the Aquadrain perimeter drainage system when they are used to waterproof basements and underground structures.
When it is known or anticipated that free water will be present behind the membrane, the installation design should incorporate adequate provision for its disposal. This will normally require the installation of one or more sump pumps.
Sentry Twin – Includes two Ama-Drainer 303 pumps and a dual power alarm. Designed for use in situations where a higher level of water ingress is anticipated or where additional backup is required. Dual outlet pipes allow both pumps to operate at full capacity.
