(1) For protection against mines the vehicle is fitted with a floor spall liner and 18 mm armour plate in the floor.(2) Water that freezes in a roof tile can cause the material to spall or crack.(3) A previous owner had applied a sealant to these walls, trapping water inside that had rusted the rebar and caused the blocks to crack and spall .(4) He struggled up a steep grade, slipping on the loose spall .(5) Though ornamented with beautiful huge rock-gripping bristlecones, the cliffs tend to spall off in big chunks and the ore body rock where the mine adits go clearly tends to cave in unless aggressively shored up.(6) A spall liner and mine protection carpet are installed to minimise the secondary effects of armour penetration and mines.(7) The elongation of the well bore is the result of compressive shear failure on intersecting conjugate planes, which causes pieces of the borehole wall to spall off.(8) cracks below the surface cause slabs of material to spall off(9) cracks below the surface cause slabs of material to spall off(10) When the stone peels or flakes along the bedding planes, spalling or exfoliation takes place.(11) A slick finish won't get dusty, but be careful not to get air-entrained concrete where air can get entrapped below the troweled surface, leading to spalls .(12) Frost fracture, therefore, predominantly affects cortical surfaces, where high porosity allows for absorption of more moisture, producing microcracks, spalling , and frost-potlidding when frozen.(13) Any cracks, chips, holes, dips or spalls should be repaired in order to achieve a flat surface.(14) After cooling the staircase and considerable spalling of the plaster work ceased, crews continued upstairs to finally extinguish the first floor.(15) The four supports below the main block also bore carving, now spalled beyond precise recognition.(16) You are also to check on incidence of spalling or cracking concrete on the external faces of the buildings and similarly report with recommendations and estimate of cost.
