Gravel Pack

Gravel pack is important for every water well system as it helps to ensure maximum yield and sustainable operation of the system.  

A well placed gravel pack should consist of uniform, clean & rounded grains of sand or gravel which should be matched to the choice of the screen and the analysis of the formation.

Boode gravel pack is washed & dried and contains no peat residues or humic substances. Boode gravel pack are 98.6% SiO2 and carry a Kiwa® ATA mark, according to Kiwa evaluation K240 "Sand and gravel for drinking water."
