AC37 foundation piles are specially designed to prevent subsidence of grave monuments. Only some cemeteries, depending on the condition of their soil, prescribe foundation piles to ensure the stability of grave monuments. The posts are 250 cm long and made of recycled material, which provides extra strength. In addition, they are reinforced with steel, making them resistant to different soil conditions. Our professional staff carefully pulse the posts at an angle around the grave to firmly anchor the foundation in the ground. With AC37 foundation piles you can be assured that your loved one's grave monument is supported in a sturdy and durable manner. We usually use 2 posts for a free-standing stone, 4 posts for an urn or grave monument and 6 posts for a family monument.
