Adressing the root problem
Unless the root cause of the problem is treated, ongoing repairs can be expensive. Over time such weakness can completely destroy the road.
The effects of insufficient drainage are exacerbated in the presence of salt. This can occur whether the roads are in the city or in the countryside.
For best results, Capiphon™ can be installed underneath and/or directly on the basement sub-grade during construction. It can, however, be used to great effect to stabilise and repair roads or, as in the case of Chiang Kai-shek International Airport below, runways and other paved surfaces.
Serious Alternative to Ag Pipe
Ag pipe is also called aggie, agricultural pipe, ag line etc. Capiphon also out-performs slotted pipe.
