Sovereign have a range of wood preservatives to treat timber with problems such as wood boring insects like common furniture beetle, usually called simply woodworm. Other types of active infestations are wet rot and dry rot of timber. Where rot is a problem then our fungicidal preservative can be used. Dry rot can also affect masonry and a specialist fungicide is available for treatment of stone, brick and concrete. These products are supplied under the Sovaq brand which is a range of water dilutable micro-emulsions for active infestations. Where thick sectioned timber such as joists embedded in masonry needs a wood preservative treatment then Deepkill, a thick bodied, deeply penetrating product should be used. If joist ends are too far gone following an active infestation then rather than replacing the whole joist the timber can be repaired using a Sovereign Bower Beam.
