Fountains are beautiful but complex systems whose preservation presents daunting and often contradictory challenges. The play of water over sculptured forms is compelling, with its charming plays of light and sound and cooling spray but these same features threaten a fountain's stability. Water erodes delicate surfaces, invites biological infestation and represents environmental conservation challenges. Balancing a fountain's material preservation with its operation and water conditioning needs is very complex. We work with structural and mechanical engineers, architects, owners and maintenance crews to treat deterioration and devise long term effective strageties to maintain and preserve fountains in parks, major buildings and private residences.
