what is ? isn't normal, good quality concrete waterproof? what does 'waterproof' mean? capillary absorption vs pressure permeability how can 'ordinary' concrete be damp-proofed? is there not a better option? possibly professional duty of care and responsibility! summary suggested sites for further information isn't normal, good quality concrete waterproof? in order to provide sufficient workability for proper placing & compaction and to facilitate proper mixing and transportation to site, most plant-batched concrete will contain water in excess of that required to simply hydrate the cement. as concrete hardens, this excess water leaves the concrete and creates a network of fine capillaries and internal pores. natural capillary absorption is the predominant mechanism of water transport through concrete whether or not a head of hydrostatic pressure is present. in essence, as far as water is concerned, normal concrete behaves like a dense sponge. one cubic metre of normal, good quality dry concrete will absorb the equivalent of roughly 60 litres of water in just 30 minutes! (test in accordance with bs 1881, part 122). it is the speed of this absorption that is important as this will directly affect the level of dampness, say in a basement, or the onset of reinforcement corrosion due to dissolved chlorides being carried into the concrete by water, say in a sub-sea tunnel, the tidal zone of bridge supports or from melting slush after de-icing salt has been applied. even the highest quality concrete contains a network of pores and capillaries and, without adequate damp-proofing protection, this may result in dampness or leaks causing deterioration of internal finishes, mould formation and a health hazard, especially in heated environments where damp concrete is a haven for bacterial development. where chlorides and oxygen are present, corrosion to the reinforcement will occur. where sulfates are present in the surrounding soils and groundwater, serious deterioration of the cement matrix can occur, both situations causing untold damage to the structure. » back to top what does 'waterproof' mean? british standards set out to ensure that reinforced concrete structures provide the degree of protection, internal environment and functionality required by owners or developers. the term 'waterproof' therefore conjures up a whole range of ideas. if the structure in question is to retain water, say a water storage tank, then the designer may simply work to the design requirements of the european water retaining code which sets out to limit crack width. this may be achieved by utilising a good quality, ordinary concrete, close attention to joint details and providing extra crack control reinforcement; dampness being acceptable. if on the other hand the structure is habitable or designed to house sensitive electronic equipment or valuable archives, then simply designing to the water retaining code is not sufficient. this is especially so given that ordinary good quality concrete provides little resistance to the passage of water vapour. there are several degrees of waterproofing to be considered, all loosely defined under 3 categories in bs 8102. at the lowest level, grade 1, there is 'water-tight' which simply means that water will not run or flow freely through the concrete but minor seepage and dampness is accepted; at the upper level, grades 3, there is 'damp-proof', which not only requires there to be no visible water ingress or dampness but also that very high levels of water-vapour resistance will be achieved. this applies whether or not hydrostatic pressures are present. watertight vs waterproof concrete bs en 934-2:2001 specifies absorption testing according to en 480-5:1996 for 'water resisting admixtures'. this requires prism shaped samples 40mm x 40mm x 160mm long to be stood up in water 3mm deep. interestingly, ordinary concrete samples become completely saturated within a couple of hours. the photo shows the control ordinary concrete and the sample incorporating a "waterproofing" admixture after 12 hours we must be clear here that the influence of cement replacement materials*1 and water reducing admixtures, though they may improve the apparent resistance to the inflow of water under pressure, may in fact create a finer capillary structure with the effect that capillary 'suction' is greatly increased and thus the flow of water through the concrete by capillary absorption is speeded up. "... the narrower the pores in saturated concrete, the lower its permeability. the narrower the pores, the greater the resultant capillary pressure and so the greater the influx of water ..." *2 *1 pozzolanas are materials containing reactive silica and/or alumina which on their own have little or no binding property but, when mixed with lime in the presence of water, will set and harden like a cement, i.e. on their own they don't do anything. e.g. pfa which is a by-product of coal fired electricity stations, also known as fly ash; ground granulated blastfurnace slag, a by-product of the steel industry sometimes called ggbs or slag; silica fume, a by-product of microprocessor silica production also known as csf, and metakaolin, a product associated with the china clay industry *2 dr andrew butler, transport research laboratory (trl), 'capillary absorption by concrete' (concrete july/august 1997) » back to top capillary absorption vs pressure permeability permeability is a measure of flow under an external pressure and is a property of saturated materials: the narrower the pores in saturated concrete, the lower its permeability. conversely, the narrower the pores, the greater the resultant capillary pressure and so the greater the depth of penetration and speed of ingress of water. but how important is 'pressure permeability' when compared with 'capillary absorption' in regard to water transport through concrete? "calculation of the water penetration depth during wetting showed that the speed of capillary absorption is of the order of a million times faster than permeability" *1. thus, in terms of damp-proof concrete, 'pressure permeability' is irrelevant unless the capillary absorption problem is addressed. you will appreciate, therefore, that the idea that water passes through properly compacted concrete depending on water pressure is a complete myth. *1 dr andrew butler, transport research laboratory (trl), 'capillary absorption by concrete' (concrete july/august 1997) » back to top how can 'ordinary' concrete be damp-proofed? the traditional approach has been to attempt to 'wrap up' the concrete with a 'waterproof coating' of some kind, be it a tanking system, external membrane, surface coating or built up treatment in the case of a roof. another approach is simply to accept that the structure will inevitably leak and to provide a drained cavity system inside the structure. membranes, tanking and surface coatings are invariably thin section, difficult to apply and rely heavily on the skill of the applicator to ensure integrity. if and when barrier systems fail, they may be on the wrong side of the structure (in the case of basement tanking) severely limiting the options for repair. failure may be from bad jointing, pin holing, damage during back-filling operations or simply down to poor workmanship. water or damp ingress seen on the inside of the structure may be at an area remote from the actual point of damage to the barrier system. with cavity drained structures there is a loss or reduction in internal useable space and a potential maintenance liability as problems can arise unexpectedly, for example, failed pump, drainage channels silt up, over-loading due to local burst water main and the effects of rising water tables in many cities. once such a system fails, water will usually run freely into the inner structure causing untold damage. attempted repair of a failed barrier or cavity drained system may not only cause significant delay in handing over a project
