Who wants to make storm systems watertight? Government agencies want reduction in non-point source pollution, groundwater contamination and de-watering of wetlands. Government agencies want reduction in non-point source pollution, groundwater contamination and de-watering of wetlands. State DOT’s & Municipalities want to reduce underground structural failures related to leaking pipe joints and pipe- to-structure connections. State DOT’s & Municipalities want to reduce underground structural failures related to leaking pipe joints and pipe- to-structure connections.

A FLEXIBLE CONNECTION IS AN IMPORTANT ADVANTAGE

THE GREATEST EXPENSE COMES LATER GROUT AND MORTAR CONNECTIONS CAN FAIL WITHIN IN AS LITTLE AS 2 OR 3 YEARS

A TIGHTLY GROUTED CONNECTION CAN CRACK THE PIPE

Watertight Connectors give us FLEXIBILITY QUIK-LOK CAST IN BOOT

WHEN USING CONNECTORS YOU DON’T HAVE THE VARIABLES OF LOST BRICKS, CEMENT THAT GETS CAUGHT IN THE RAIN, WAITING TO BACKFILL WHEN USING CONNECTORS YOU DON’T HAVE THE VARIABLES OF LOST BRICKS, CEMENT THAT GETS CAUGHT IN THE RAIN, WAITING TO BACKFILL THAT’S IMPORTANT WHEN THERE ARE 100 STRUCTURES ON THE JOB

What Cost-Benefits Do Watertight Systems Provide? Lower Total Labor and Material Costs Lower Total Labor and Material Costs Faster & Less Expensive Installations Faster & Less Expensive Installations Higher Quality Product at same Cost Higher Quality Product at same Cost

EASY INSTALLATION !

A-LOK GUARANTEE When properly installed we guarantee our connectors not to leak for the connectors not to leak for the life of the structure!

Flexible rubber connectors in storm sewers create a win- win situation! When precast products with watertight connectors are manufactured in a controlled environment consultants turn over a better product to owners. When precast products with watertight connectors are manufactured in a controlled environment consultants turn over a better product to owners. Contractors benefit because connectors Contractors benefit because connectors are more cost effective than brick and mortar. are more cost effective than brick and mortar. Municipalities get a watertight system, longer service & less maintenance Municipalities get a watertight system, longer service & less maintenance

Summary: Prevention is more cost-effective than repair but requires changing the way we think and do things today.
