The parties are close family members involved in a long-standing sand mining business that was divided in 2005. Under a separation agreement, the appellants took business assets and assumed responsibility to rehabilitate mined land (Portion 3 of Farm 442 Londondale), while the respondents received ownership of that land. Due to the appellants’ failure to rehabilitate the land, the respondents instituted a monetary claim for rehabilitation costs. During trial in 2014, the parties concluded a settlement agreement, made an order of court, in terms of which the appellants undertook to deliver 100 000m³ of ‘clean sand’ (excluding topsoil) within six months, stockpiled near a weighbridge on a different farm (Boschbank 12). The respondents later alleged that the appellants breached the agreement by delivering material that was not clean sand, was inadequately stockpiled, and was delivered late. They claimed payment of R15 million or alternative relief. The appellants contended that they had complied and that ‘clean sand’ meant sand suitable for rehabilitation, not necessarily commercially valuable sand.
