Claim:
A method of forming a structural support system comprising: positioning a hollow, base form at a first elevation, said base form having an upper surface and a lower surface, said lower surface having a greater periphery than said upper surface; positioning a hollow column form having an upper open end on the upper surface of said base, said hollows in said base form and said column form being in open communication; said column form comprising: first and second L-shaped sections, said first L-shaped section comprising a first leg and a second leg adjoined to form a first corner, a first chamfer forming member disposed adjacent said first corner, said first leg having a first flange extending laterally outwardly from the end of said first leg distal said first corner, said second leg having a second flange extending laterally outwardly from the edge of said second leg distal said first corner; said second L-shaped member comprising a third leg and a fourth leg adjoined to form a second corner, a second chamfer forming member disposed adjacent said second corner, said third leg having a third flange extending laterally outwardly from the end of said third leg distal said second corner, said fourth leg having a fourth flange extending laterally outwardly from the end of said fourth leg distal said second corner, said first and second flanges being generally coplanar, said third and fourth flanges being generally coplanar; disposing a first T-shaped seal having a first T-leg between said first and third flanges, said first T-seal having a second T-leg transverse to said first T-leg, and forming a third chamfer forming member; disposing a second T-shaped seal having a third T-leg between said second and fourth flanges, said second T-seal having a fourth T-leg transverse to said third T-leg and forming a fourth chamfer forming member; forcing said first and third flanges into engagement with said first T-leg of said first T-seal; forcing said second and fourth flanges into engagement with said fourth T-leg of said second T-seal; and introducing a curable material into the upper open end of said second form whereby said curable material fills said hollows in said column form and said base form.
