Maxima are water matrix blocks that can be installed in lined excavations to create weight-bearing underground water storage. They allow more water in a smaller volume thanks to 96% void space and therefore reduction of the overall size of the pond.  

Maxima lock together quickly and securely and offer limitless arrangements of the modular blocks and accommodate almost any pond.  They support landscaping, paving slabs or gravel for a great design versatility. Excellent for bog construction to create settling chambers below natural plantings.
