Hi, I have to install an array of VWP's along the base of an old opencut quarry (approx. 90m deep)that is going to be filled with engineered fill. (houses built above) there will be there to monitor the infiltration rate and pore pressures. The only problem is that the Piezometers I am used to all need water in the filter during installation. It might be months before the water table (if it ever does) infiltrates to the VWP's (laid in a trench). And am concerned that they will dry out and when the water does eventually get to the VWP's the air bubble between the mesh and the sensor will remain and the data will be useless. will water eventually soak in through the Mesh (steel or ceramic)??(I didn't think it would)Ideas??
