An elongated joint seal for sealing a gap between two surfaces, comprising a trunk and at least two resilient members extending one to each side of the trunk, the fingers in use contacting the surfaces of the gap, the trunk being substantially rigid to enable insertion of the seal into the gap.
A joint seal for sealing a gap between two surfaces, comprising:
- an elongated strip of resilient material having sealing members extending laterally to one side of the strip;
- and
- a substantially rigid spine for driving the elongated strip into a gap whereby the spine folds the strip along the width of the strip into the gap to form a substantially rigid trunk encapsulating the rigid spine whereby at least one sealing member locates on opposite sides of the trunk so as to contact the surfaces of the gap.
A method of sealing a joint gap between two surfaces comprising:
- aligning along the gap an elongated sealing strip of resilient material having sealing members extending to one side of the strip;
- driving the strip into the gap by forcing a substantially rigid spine along a longitudinal line of the strip such that the strip folds as it is driven into the gap and the members contact the surfaces on either side of the gap.
