The steel bars requires a concrete 40mm concrete cover from the ring. Often however there is no concrete cover or due to reasons like (Honeycombing, cold joints, patla mal --watery concrete-- dampness and bad workmanship) moisture attacks the steel bars and leads to corrosion problems and slow disintegration of concrete in 8-12 years.
Span arrests this Concrete Cancer and the ‘explosion in slow motion’ - a term coined by Mr. A.P. Remedios.
Chemicals such as Ruskill a rust passivator/ converter -- using “Saint Gobain” – Cem-Fil, Anti –crak HD alkali resistant glass fibre for concrete and plaster and increasing the concrete cover Span can offer a 30 – 40 year no issue guarantee.
Brick Bat Coba used in the construction for slope to drain the rain water to the rain water pipes normally do not have the required slope span ensures this. Brick bat coba also provides insulation to the slab has wrongly mistaken for waterproofing.
Span offers a screed of 1:1/2: 2 mix is laid to bond with the existing slab thus thickening it by about 40 mm -in this process bars which do not have concrete cover are covered too.
A Bitumen Membrane ISI make Shalimar 3 mm /plastomeric waterproofing membrane using heated cold tar stuck on the slab with a lap of 4 inches. China mosaic is preferred to IPS as it reflects 27-30% of the heat—every 3 / 4 years, due to expansion contraction cracking occurs and china mosaic moves expand and contracts without damaging the upper layer of the waterproofing system.
Span re-concretes a screed of 1:1/2: 2 mix is laid to bond with the existing slab thus thickening it by about 40 mm -in this process bars which do not have concrete cover are covered curing for 7 days and then repeats the bitumen process above followed by china mosaic with curing . additionally the screed goes below the parapet wall – 3 feet at a time thus guaranteeing the entire length and breath of the terrace.
All our concrete work is compacted properly and cement is used correctly keeping its time related efficacy in mind. Recasting of slabs and beams where required. We offer perfect plastering with superior techniques ensuring common issues of pulling away and hairline cracks are solved permanently. Resurfacing of bricks if required to bring to plumb line as poor brick quality is being used throughout the building industry while re-plastering is also undertaken.
Span checks problems with corroded steel bars in columns, beams and slabs. Rust occupies three times its original steel volume resulting in expansion, thereby splitting the concrete surround the bars, because concrete is weak in tension and cracking in concrete occurs. Hence if the rings are corroded rebar’s welded in place or jacketing is done. Jacketing is a technique of encasing a damaged RCC member in a 100 mm thickness RCC shell.
All our concrete work is compacted properly and cement is used correctly keeping its time related efficacy in mind. Recasting of slabs and beams where required We offer perfect plastering with superior techniques ensuring common issues of pulling away and hairline cracks are solved permanently. Span constructions masons are trained not to use this dry cement powder and if the thickness of plaster is required for line level (some times the entire building plaster in certain areas are out of plum by 3 to 4 inches) a layer method of ½ in to ¾ inch is adopted – a technique by taught by guru A.P. Remedios.
Masons are constantly using the short cut method --- dry cement powder while plastering in order to get quick line level this quickens the setting of cement – thus increasing the area covered in plaster and thickness (using this method up to 3 inches thickness of plaster can be completed in one go) which increases production but reduces the quality of plaster –this is the precise reason that plaster de-bonds and separates from the parent body of the building and cracking after 2 to 3 years.
Resurfacing of bricks(coating in cement mortar in layers) if required to bring in plumb line as poor brick quality is being used throughout the building industry before re-plastering is done.
