Inquiry (采购产品): Sealant for Porous Rock Dear Sir: We recently had a landscaper install a water feature in our back yard here in Honolulu. It is made of lava type rock stacked about 5 feet high by 10 feet wide with a pipe at the upper level dispensing water over four tiered levels of rock to the pond below (where it is filtered and pumped back to the top again). Since the fountain was completed we have had continuous problems with water leaking between the rocks. The landscaper has come back on 5 or 6 occasions to apply cement and various sealers over the rock but has not been able to stop the leak. The fountain is exposed to the sun most of the day and the average daytime temperature here is around 75 degrees year round. Do you have any suggestions for a sealant type that might work for us?
