ATLAS MASONRY MORTAR is produced as a dry mixture of the highest quality cement binder, quartz fillers and refin-ing additives. Compressive strength – category M5. Factory made – guarantees uniform working parameters of the mortar and technological parameters of the joints after setting.
concrete masonry construction details and other pertinent information. It is recommended that users of this manual contact local manufacturers regarding availability of particular sizes and configurations of concrete masonry units
• Recommended for traditional thick joint masonry - it allows for correction of dimensional inaccuracies in wall elements. • Allows the construction of overground storeys, basement walls and foundations - reinforced and unreinforced subject to struc-tural requirements.

• Specification of mortars for masonry construction (incl. strengths, mixes etc.) • Recommendations for site operatives • Guidance for ‘good practice’ on site. • Guidance on the specification of design requirements for required workmanship • Provides minimum wall thicknesses for low rise construction (2C5)
Placement: At first course above grade and at all supports. Code required spacing: 33” o.c. MIW recommended spacing (Brick): 24” o.c. MIW recommended spacing (CMU): 32” o.c. Size: The bigger the weep hole is, the more water it allows out of the cavity and the more air it allows to circulate through the cavity.
Mortar should comply with Standard Specification for Mortar for Unit Masonry, ASTM C 270 (ref. 9). In addition, most building codes require the use of Type M or S mortar for construction of basement walls (refs. 2, 4, 5, 9, 13), because Type M and S mortars provide higher compressive strengths.
